Stop sneaking Train purchases into the house....
Step one; track your delivery online through the carriers’ website.
Step two; on the morning you discover the package is on the truck for delivery, conspicuously hang this in front of your house.
Step three; when your package arrives make a big deal out of it; jumping up and down like a little kid while proclaiming how wonderful Santa Claus is.
Step four; when the significant authority questions your newest train purchases refer said authority to step two.
Step five; when authority still shows doubt and turns away in disbelief, ring this…
Step six; when authority turns to towards the sound of step five; Congratulations! You have succeeded because as everyone knows, anyone who hears the bell ring must BELIEVE!
